Update.
1998-05-15 21:07  Ulrich Drepper  <drepper@cygnus.com>

	* iconv/gconv.h (gconv_step_data): Add new fields invocation_counter
	and internal_use.
	* iconv/gconv_open.c (__gconv_open): Initialize invocation_counter
	and internal_use.
	* iconv/skeleton.c: Increment invocation_counter.
	* iconvdata/iso-2022-kr.c: When used in iconv() emit designator
	sequence first.

	* iconv/skeleton.c (FROM_DIRECTION): Completely embrace expression.
	* iconvdata/iso-2022-jp.c: Likewise.
	* iconvdata/iso646.c: Likewise.

	* iconvdata/Makefile: Correct rpath definition for ISO-2022-KR.
